CHARLES M. BERRY, 01? NEW YORK, N. Y., ASSIGNOR OF ROSENBERG, OF NEWYORK, N. Y.

ONE-HALF T0 BERNARD WINDOW-FASTENER.

Application filed February 9, 1910.

To all whom a may concern:

Be it known that 1, CHARLES M. Bnnnr, a citizen of the United States,and a resident of the city of New York, borough of Manhattan, in thecounty and State of New York, have invented a new and ImprovedVVindow-Fastener, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improved windowfastener, arranged to securely fasten both the upper and lower sashes inclosed position, and to hold the same against opening from the outside,at the same time preventing rattling.

For the purpose mentioned, use is made of a screw rod screwing in a nutmounted to swing in a bearing plate attached to the window frame, at apoint immediately above the top of the lower sash at the time the latteris closed, so as to permit of extending the screw rod across the top ofthe lower sash, to engage the upper sash and thus lock both sashesagainst opening from the outside.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in bothviews.

Figure l is a cross section of a window provided with the fastener,shown in active position for fastening the upper and lower sashes inplace: and Fig. 2 is a sectional side elevation of the same on the line2-2 of Fig. 1.

A bearing plate A is fastened by screws B to thestop bead G of thewindow frame, at a point somewhat above the top of the lower sash D, atthe time the latter is in a closed position. On the bearing plate A ispivoted a nut E, in which screws a screw rod F, provided at its outerend with a handle F and at its inner end with a head F adapted to engagethe upper sash D, as plainly indicated in Fig. 1. Now by the arrangementdescribed, the nut E is mounted to swing so as to extend the forward endof the screw rod F across the top of the lower sash D, at the time thelatter is in a closed position, and at the same time the head F of thescrew rod F'engages the upper sash D, to lock the same against openingor downward movement. Now as the screw rod F extends across the top ofthe lower sash D, the latter cannot be pushed upward into anSpecification of Letters Patent.

open position, and consequently both sashes D and D are held againstopening. The bearing plate A and the nut E are so arranged that thescrew rod F is slightly iiiclined in a downward direction, so that anyupward movement of the lower sash D tightens the screw rod F relative tothe upper sash D, thereby preventing opening of the sashes from theoutside by unauthorized persons.

The head F is movable on the end of the screw rod F (see for comparisonfull and dotted lines in Fig. 1), so that the full face of the head Fbears against the sash at the time the screw rod is inclined downwardly,as shown in Fig. l, and hence a firm hold is had by the head on theupper sash D to prevent the same from being opened. It will be noticedthat the screw rod F may also be used for locking the lower sash D in araised position, as the screw rod F is threaded its entire length andhence can be screwed inward to clear and allow of raising the lower sashD, after which the screw rod F may be screwed outward to engage and holdthe lower sash D in the raised position.

When the device is not to be used for locking the sashes in place, thenthe operator unscrews the screw rod F, to disengage the head F from theupper sash D, and then swings the screw rod F with its nut E into avertical position, as indicated in dotted lines in Fig. 1, to move thescrew rod 'F completely out of the path of the lower sash D, thusallowing an opening and closing of the sashes.

As shown in Fig. 2, the nut E is provided with a pivot E, engaging acorresponding hearing A in the bearing plate A, and a head E is rivetedor otherwise formed on the pivot E, to engage the inner face of thebearing A, to hold the pivot E in position in the said bearing.

By the arrangement shown and described, the pivot E and the bearingplate A can be readily assembled, and when assembled, the fastener canbe quickly attached to the stop bead G by the screws B, as previouslymentioned and shown in the drawings.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent:

A window fastener, comprising a bearing plate, a nut having a pivotengaging the said bearing plate, and a screw rod screwing in the saidnot and provided at one end with a handle and at the oth end with amovable head, the threads of the screw rod extending the entire lengthof the rod to permit of engaging the said head with either the upper orthe lower sash, the said hearing piste being arranged for attachment tothe window easing at a point above the top of the lower sash at the timethe latter is in a closed position, to permit of extending the screw rodin a down *ardiy-inciined direction. across the top of the lower sash toengage the foil face of the screw rod head with the upper sash, thescrew rod when complete-1y retracted clearing the lower sash to allowopening thereof and to engage the head oi. the screw rod with the lowersash to lock the latter in a raised position.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
